I've had the koni/Cobb setup. You won't be disappointed. Just keep access to the rear dampening adjustment knobs free for a while to get your setup dialed in. Just switched to bc/br an they're not as terrible as I would have thought. If you've got a set of cobbs that have any rake in them I'd suggest putting some whitline etc. part in to adjust the camber in the rear.

Good to hear! I am also having the Whiteline LCA bushing and Anti-Lift kit installed at the same time. That matched with the Cobb rear swaybar should be a nice set up.
